Roll welding device for precast pile reinforcement cage framework

Abstract

The invention provides a roll welding device for a precast pile reinforcement cage framework. The roll welding device comprises a rotary table mechanism, a straightening mechanism and a welding mechanism, wherein the straightening mechanism and the welding mechanism are arranged on the two sides of the rotary table mechanism, the rotary table mechanism and the welding mechanism are in signal connection with a controller, the rotary table mechanism comprises a base, a drawing device, a diameter adjusting device and a supporting device, the drawing device, the diameter adjusting device and the supporting device are arranged above the base and are parallel to each other, the drawing device and the supporting device are located on the two sides of the diameter adjusting device respectively, the diameter adjusting device and the drawing device are connected through a connecting shaft, the diameter adjusting device and the supporting device are connected through a connecting shaft respectively, a plurality of second lifting devices are arranged between the diameter adjusting device and the drawing device, and a plurality of first lifting devices are arranged between the diameter adjusting device and the supporting device. According to the roll welding device for the precast pile reinforcement cage framework, displacement of the reinforcement cage can be conducted through the drawing device, diameter changing in the production process of the reinforcement cage can be conducted through the diameter adjusting device, framework ribs are pre-straightened through the supporting device so as to release tension and torsion, operation is easy, and the product precision is high.

Description

technical field [0001] The invention belongs to the technical field of seam welding machines, and in particular relates to a seam welding device for a prefabricated pile reinforcement cage skeleton. Background technique [0002] The steel cage roll welding machine can produce multiple steel cages with different diameters and specifications. In the prior art, when the specifications are changed, each welding slider assembly installed on the front wheel will expand in the front wheel slideway at the same time under the traction of the driving mechanism. Or shrink, mostly chain transmission and multiple motors are installed, the synchronization of multiple motors is very poor when the diameter is changed, and the displacement size is difficult to guarantee when the diameter is changed by a large margin. If the offset is too large, the bones and tendons Excessive tension will cause serious production accidents, especially involving too many transmission motors. An abnormality in...
